Let's divide 90192172 by 817
Our goal is to divide 90192172 by 817.

Advancing to step 1:
If we divide 9 by 817, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 817

Moving on to step 2:
90 divided by 817 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 817

Advancing to step 3:
The number 817 fits into 901 1 times, leaving a remainder of 84.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 817 from 901 leaves us with 84.
Grab the next digit (9) from the dividend, add it to 84, then carry on: 849 / 817

Let's proceed to step 4:
If we divide 849 by 817, we get 1 and a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 817 away from 849, we end up with 32.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 817

Let's proceed to step 5:
The number 817 fits into 322 0 times, leaving a remainder of 322.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
If we subtract 0 from 322, we get 322.
Bring next digit (1) of the dividend behind the 322 and repeat the process: 3221 / 817

Step 6:
3221 divided by 817 is 3 with a remainder of 770.
The number 3 becomes the next digit in our result. 
Result so far: 1103.0
The remainder is 770 after subtracting 2451 from 3221.
Grab the next digit (7) from the dividend, add it to 770, then carry on: 7707 / 817

Let's proceed to step 7:
The number 817 fits into 7707 9 times, leaving a remainder of 354.
Record the quotient 9 as the next digit in the result. 
Result so far: 11039.0
Subtract 7353 from 7707 to get 354.
Take the next digit (2) from the dividend and append it to 354, then repeat: 3542 / 817

On to step 8:
The number 817 fits into 3542 4 times, leaving a remainder of 274.
Write down 4 as next digit of the result. 
Result so far: 110394.0
Deduct 3268 from 3542 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 9:
2740 divided by 817 is 3 with a remainder of 289.
Write down 3 as next digit of the result. 
Result so far: 110394.3
If we take 2451 away from 2740, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 10:
817 can be fit into 2890 3 times, resulting in a remainder of 439.
Record the quotient 3 as the next digit in the result. 
Result so far: 110394.33
Deduct 2451 from 2890 and we're left with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

The final result is 110394.33 with a remainder of 0.439.
